Guidance to the optimal point for freeze-drying a hydrogel
Freeze-drying is a common method to produce porous scaffolds from a hydrogel composed of natural or synthetic polymers. In a number of cases, the polymeric solution is crosslinked (bonds or interactions are established among the polymeric chains) and the hydrogel is then freeze-dried to obtain the porous and dried scaffold (1-3).
